Abstract: HTR - 2000 developed for arithmetical control of pebble bed high temperature reactors with multiple process - is closely coupled to the actual operation of the reactor. Using measured nuclear and thermo-hydraulical parameters as well as detailed model of pebble flow and exact information and fuel burnup, loading and discharge it obtains an excellent simulation of the status of the reactor. The geometry is modelled in three dimensions, so asymmetries in core texture can be taken into acount for nuclear and thermohydraulical calculations. A continuous simulation was performed during five years of AVR operation. The comparison between calculated and measured data was very satisfying. In addition, experiments which re-calculating the control rod metical analysis shows that at sorber in the reactor core the split reactivity worth for single absorbers can be determined by calculation but not by methods of measuring.
